Do You Need a Permit to Build a Fence in Brockville? (Height Rules & Bylaw)
Last updated: June 2026
No building permit is required to install a fence in Brockville — but you must build to the City's Zoning By-law 050-2014 and confirm your property lines first. In residential zones, fences are limited to 2.0 metres (about 6.5 ft) in side and rear yards and 1.0 metre (about 3.3 ft) in front yards. Barbed wire, razor wire, spire tips, and electrically charged fences are not permitted in residential zones. Height is measured from grade and includes any lattice or fence topper.
Do you need a permit to build a fence in Brockville?
No — Brockville does not require a building permit for a residential fence. However, you are required to confirm the location of your property lines before installation begins, and the fence must comply with Zoning By-law 050-2014. A pool fence is a separate requirement — see Ontario pool fence rules.
How high can a fence be in Brockville?
In residential zones, fences may be up to 2.0 m (6.5 ft) in side and rear yards and 1.0 m (3.3 ft) in front yards. Height is measured from grade and includes lattice or other toppers.
| Location | Max height | Notes |
|---|---|---|
| Side & rear yard (residential) | 2.0 m (≈6.5 ft) | Includes lattice/toppers, measured from grade |
| Front yard (residential) | 1.0 m (≈3.3 ft) | Applies to fences, walls & unpierced hedgerows |
| Other zones (most) | 2.0 m | Except Open Space / Institutional |
| Commercial/Employment security fence | 2.5 m | Barbed wire limited & conditional |
What types of fences are not allowed in Brockville?
Barbed wire, razor wire, spire tips, sharp objects, and electrically charged fences are prohibited in residential zones. Barbed wire is allowed only on commercial/employment security fences under strict conditions (max 3 strands, 2.0 m above grade, no overhang toward the lot line).
What about corner lots and property lines?
Fences must stay within your property boundaries and out of the corner-lot visibility triangle, which restricts height near intersections for traffic sightlines. Confirm your property lines (a survey) before you build — Brockville requires this. Encroaching a neighbour's line or the sight triangle is the most common compliance problem.

How is fence height measured in Brockville?
From grade (ground level) to the top, including any lattice or decorative topper — so a 1.8 m fence with 0.3 m of lattice counts as 2.1 m and would exceed the 2.0 m residential limit.
